Drinking & Wasterwater treatment
Risk analysis includes multiple steps which are: Input: Output:
I. Define the source and type of pollutants Body Weight The Chromium Daily Intake (CDI) is {{CDI() | number: '9'}} mg/kg-day
II. Identify the pathway (e.g. water) Risk The output concentration is {{ActualOutCon() | number: '9'}} mg/cu.m
III. Identify the receptor Air volume inhaled /day The concentration {{passfail()}}
IV. Define the effect Potency Factor
V. Decide the acceptable risk Allowbale CDI concentration
VI. Calculate acceptable levels of pollution
VII. Design treatment strategies
